I saw that one. I like the idea of the vernier tang sight for long range target. I would recomend that he try the same front sight I have on my 458. It is a Lee Shavers globe sight with a level. That thing rocks for keeping your gun lined up right. If a guy wants to go out to 300 yards the Lyman 57 will do that. If a guy is using a rifle like my .458 I would need a vernier tang sight to get to 300 yards with a 450 + grain bullet. The Lee shavers sight comes with several different cards including the fine pin which is what I use. It also has a crosshair that I like a lot too. Ron
